Creating file names.

Gregg

You could either manipulate the character returned by today(), or try
using Sys.time() instead.  For example, on Windows,

paste(strsplit(date(), ' ')[[1]][c(2,3,5,4)], collapse='_')

gives

Jan_09_2009_13:40:57

which approaches what you want.  Alternatively

format(Sys.time(), "%b_%d_%y_%H%M")

gives

Jan_09_09_1342

which only needs LMSMOD pasted to the front which sep='_'.

Subject: [R] Creating file names.

I have a function that is called from a "sourced" script, 
whenever certain conditions are met.

I have this inside it:  if(P > 0.9)save( file = today() , 
myLMSmodel );


This gives me files that look like this: Thu Jan  8 14:04:43 2009

That works fine on my Mac, but it would be much more 
convenient to have something like this:

LMSMOD_Jan_08_09_1404


Does anyone know how I can do this?

(You don't have to put in the underscores, if it's too much work.)

Thanks,


Gregg Allen
